' Application filed July 13, 1917. Serial No. 180,415.

To all whom it mag concern Be it known that I, Cnannxcn B. WADE, a citizen of the United States, residing at American Falls, in the county of Power and State of Idaho, have invented certain new and useful Improvements in Gas-Generators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled'in the art to which it appertains to make and use the same.

The invention relates to improvements in gas generators.

The object cf the present invention is to improve the construction of gas generators and to provide a simple, practicalv and efficient apparatus of comparatively inexpensive construction designed for generating gas from kerosene or distillate for storage in a tank or drum for use for heating,'lighting, etc., a portion of the gas as generated being utilized to supply the burner employed to furnish the heatto vaporize and gasify the kerosene or otherhydro-carbon.

A further object of "the invention is to provide a gas generatorof'this character adapted to be usedin one or more unitsand to be conveniently installed in stoves, furnaces or elsewhere, either for furnishing the heating means for the same or primarily for the generation of gas for use in other heating or lighting devices.

lVith these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawings and pointed out in the claims hereto appended; itbeing understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention. In the drawings: Figure 1 isa side elevation of a gas generator constructed in accordance with. this invention.

flange 2 and having a centrally arrang the inner casingfitsthe interior of the same.

concavo-convex top and bottoni walls ls the invention, the gas generator comprises. I in its 'COllStlUCtlOll a base'l constructed of suitable metal and prov ded Wltlla marg'in flanged opening The base plate, which ,6 0'-- may be constructed of a size to receive one" or more units of the gas generator, forms" a pan which is adapted to be used as a start? ing receptacle and also as a water pan for supplying moisture? to the gas generator. L Thebase is provided with spaced posts upon which-is mounted a supporting plate '5 of circular form provided. at its upper face t adjacent 'to 'its periphery with an annular vertically disposed flange 6 and having its outer edge portion forming asupporting ledge 7 for a cylindrical shell or casing 8.

T he supporting plate has a central opening 9 and supports'an inner shell or casing-10, consisting'of inner andlouter cylindricalv 7. walls 11 and 1'2 and'a horizontalconnecting top plate or wall 13 and forming a central upwardly'tapered passage. ll.- Theinner casing and the'outer she'll are arranged" in spaced relation to provide an intervenmg r space 15 through which a mixture of g'as,- vapor, air and moisturepasses to outlet per; forations 1.6 of the outer, shell. The 'oute' shell fits exteriorly aroundthe flange 6 jand' The inner casing preferably hasflits top. wall located below the plane of theflippeii edge of the outer shell, the central passage ll having a slight upward taper, as clearly p shown. in 30f the drawings, andlhe 9Q outer shell supports a top casing. 17 ha ng g,

. 1d 19 and acylindrical, side wall 20.conne ct1 ngj v the top and" bottom' walls. The bottoin'. 'wa-ll 1 and the top wall present upper 'conveirsur '9'5 faces and lower concave surfaces andthe' bottom wall forms a dome over the inner casing and provides ,a space for mixing the i I air, as, vaporand moisture, This mixi igi space or chamber 21, formed by the conca'ver100; lower face of the top casing, is located above I the passage 14 and is arranged centrally with relation to the same. The top-casing, which forms a drying and g'asifyingchain. 1 ber22. is provided at the lower edge of zit he lob.

cylindrical side wall 20 with a dependingf; flange 23 which is recessed at theinner: face i to receive the upper edge of'tlie outer-"shell whereby the top casing is firmly seated upon the outer shell. The concave "face of the 1-10 vaporizing coil 28' and'are pierced by bolts 29 which secure clamping members 30 in enr.

' end 25. to the top casing at the upper por-- 10 tlO11"i he 1 B0f and. an inlet opening 26' which dome of the mixing chamber directs the mixture outwardly and deflects the same downwardly to the annular space 15.

The nixture burns ext-erio'rly of the outer shell 8, and the flame directly impinges against an exterior vaporizing coil 2a which may consist of anydesirednumber ofeonvolutions, and which is connected at its upper is preferably flanged, as shown. Thebottom supporting plate is pmvided with supporting arms .27, )referably four i i-number,

and they are arranged diametrioally of the supporting plate for receiving an auxiliary gagement with the'auxiliary vaporizing coil for maintaining the same firmly upon the supporting arms. The main vaporizing coil 2i and the auxiliary coil 28 are connected by branches '31 and 32 with a supply pipe 33 in communication with a suitable tankor reservoir of kerosene or other hydrp-carbon" or fuel and the flow of such fuel to the coils may be controlled by suitable needle valves of which the operating stems 3 c and 35 are shown in Fig 1. The-other end of the coil 28 is connected 'bya branch 36 with a casing 37 preferably in the form of a a union and provided with chambers or compartments 38 'and39 and located' beneath the central passage or opening ll of. the inner shell or casing; The top wall of the'cnamber 38', in which tliereis a suitable openinyghas a nozzle 40 arranged to discharge centrally of the passage 14 for supplying vapor from the auxiliary coil'28, and mounted in the lower wall of the casingis a threaded stem l1 carrying needle 42 arranged to be moved into and out of theopening of the nozzle for *the purpose of removing.foreigirmatter therefrom.

The stem extends downwardly through the flanged opening 3 of the base-2, The other chamber 39 is provided in its top wall with a. nozzle 43 set at an angle and arranged to discharge into the opening or passage ll of the inner casing so as to inter- ;sect the .vapor from the nozzle l0 'andmin' with the same at the point'where the vapor enters the pz'issage or opening ll. The compart-nie'nt or chamber 39 is connected with a pipe ll communicating.with the gas storage tank (not shown) and equipped with a needle;

valve having an operating stein l5 which controls the passage ofthe gas 'to the nozzle 43.

The top casing is provided with an outlet 46 for the gas and isconnected by a pipe 47 with the said storage tankor drum (not shown), and with which the pipe 44.15 also connetediflr i The apparatus is: equipped with a water tank or receptacle 48having a pipe 49. leadiiig to the pan or basin of the'base; 1, and 1 having a controlling valve 50.. The pan is adapted to hold suitable fuel such as kerosene, alcohol or the like, for supplying the initial heat to start the generator.

The gas from the-storage tank may be used in the starting and operation of the burner of the generator and it can be used in fconjunction with the vaporized fuel, or

the vaporized fuel after the starting of the generatorin'a-y be used without the gas. The generator; after being started, is supplied with moisture from the water tank, the water being allowed to drip'into the receptacle of the base so that the heat of the generator will vaporize the water delivered to .the base and the'suction or upward draft of the gas'and vapor through the central passage of the inner casing will cause tlie'water Vapor or moisture to be carried upward with the discharged gas and vaporized fuel, whichwill also draw into the central opening and the mixing chamber air to combine with the gas and vaporized fuel and moisture to provide a mixture to burn eXteriorly of the per. forated shelL'a-nd the flame will burn with blast force and generate sufficient heat to heat the coils 2i and 28 for vaporizing the kerosene which passes into the top gasing in the form oft a. vapor and is highly heated and dried therein before passing .to the storage tank. The hollow inner shell or casing forms a dead air space and while theco'nstruction shown is preferable 1t may be of course varied without changing the general arrangement or principle of. operation. Various kinds of fuel may be employed and the gas generator is adapted to utilize the gas generated for operating the burner and also to vaporize a quantity of the fuel for snot purpose, and the vaporized fuel and the gas vmay be employed independently or simultaneously.
